The purpose of a compressor safety valve is to?

• A. Increase system pressure.
• B. Control and limit pressure buildup to prevent over-pressurization.
• C. Vent coolant.
• D. Adjust motor RPM.

Answer: (B)

A compressor safety valve is a protective device that prevents over-pressurization by automatically releasing fluid when the pressure reaches a set limit. It stays closed during normal operation and opens to vent enough gas to bring the pressure back down, then reseals as pressure drops. This prevents damage or danger from pressures that could exceed what the equipment can safely handle. It’s not used to raise pressure, vent coolant, or adjust motor RPM—the valve’s purpose is to relieve excessive pressure, protecting the system and personnel.
